"had not given /usr it's own partition" This is always a matter of choice. /usr does not have to be it's own partition. Putting /usr on a second disk may be more confusing than leaving it where it is. If you were moving /var to a different disk, not as bad but to move /usr requires you boot up off of a cdrom into single user.

"The www files are all under /usr" Are they under /usr in their own directory? If so, that is what you should move to it's own partition (leaving /usr where it is). If they are in /usr/www/, then boot into single user and tar the /usr/www/* and put it on the second disk. Then create a link from /usr/www to the new directory on the second disk (/www). This is also better for security reasons not to have the web pages (and cgi-scripts) loaded on /usr. You probably don't have to change the Apach config files at all for this (although that is also easy enough)

NAME

       installboot - install bootblocks in a disk partition

SYNOPSIS

       installboot bootblk raw-disk-device

       The boot(1M) program, ufsboot, is loaded from disk by the bootblock program which resides in the boot area of a disk partition.

       The  ufs  boot objects are platform-dependent, and reside in the /usr/platform/platform-name/lib/fs/ufs directory. The platform name can be
       found using the -i option of uname(1).

       The installboot utility is a SPARC only program. It is not supported on the  architecture.  users should use installgrub(1M) instead.

       bootblk	       The name of the bootblock code.

       raw-disk-device The name of the disk device onto which the bootblock code is to be installed; it must be a character device which is  read-
		       able and writable. Naming conventions for a SCSI or IPI drive are c?t?d?s? and c?d?s? for an IDE drive.

       Example 1: Installing UFS Boot Block

       To install a ufs boot block on slice 0 of target 0 on controller 1 of the platform where the command is being run, use:

	      example# installboot /usr/platform/`uname -i`/lib/fs/ufs/bootblk 
		   /dev/rdsk/c1t0d0s0

       /usr/platform/platform-name/lib/fs/ufs

	   directory where ufs boot objects reside.

       /platform/platform-name/ufsboot

	   second level program to boot from a disk or CD

WARNINGS

       The installboot utility fails if the bootblk or openfirmware files do not exist or if the raw disk device is not a character device.
